"Non-negativity certificates on real projective curves"

How can one use sums of squares to characterize nonnegative polynomials? In this talk, we will review some general methods for certifying that a polynomial is nonnegative on a real projective subvariety.  We will then present new optimal degree bounds for certificates on real projective curves.  This talk is based on joint work with Grigoriy Belkherman and Mauricio Velasco.

Refreshments will be served in MC 5403 at 3:30pm. All are welcome!
